XV editor in script mode needed to reduce pic size

[bruce1271]

I would like to use xv to convert my .jpg to 50% of its original size. I dont want ot use the gui for 50 pics. Is ther ea way to use xv as a script?? or is there a program called convert or something?? thanks

Sure:

convert -geometry 50% <input> <output>

To process a whole bunch of images at once, try this script (run it in the dir with the pictures you need converted, or, better yet, a copy of that dir, since I'm not 100% certain this won't screw something up; I tested it but still... ;) ):

for i in `ls`; do convert -geometry 50% "$i" small_"$i"; done

Special note: this script won't do files with spaces. Maybe someone smarter than I can figure that one out...
